<Cocoa / Cocoa.h> location

Question

I'm new to Mac OS X development. In the Xcode / Cocoa developer environment, every Objective-C project starts with
#import <Cocoa/Cocoa.h>
It works fine, but I'm puzzled by the location of the Cocoa.h file. On my file system, there is no Cocoa.h file in the Cocoa folder. I tried "find / Cocoa / Cocoa.h" and "find Cocoa / Cocoa.h" nothing was found.
Can someone give me a hint about how and where the compiler finds the Cocoa.h header in the #import expression above.

Thanks, Microsoft Addict Recovery
